The Duke researchers looked at eight different imaging technologies among 100,000 cancer patients between 1999 and 2006. While 2-year costs of overall care per patient rose 2-5 percent, the cost of imaging rose 5-10 percent per patient over the same period, the researchers found.
The use of PET scans rose the fastest, according to the release. Imaging costs make up 6 percent of the total Medicare budget for cancer patients.
